WAGON-PERCH-CROTCH COUPLING.

SPECIFICATION forming part of Letters Patent No. 400,045, dated March 26, 1889. Application filed December 15, 1888. Serial No. 293,677. (No model.)

To all whom it may concern:

Be it known that I, THOMAS E. BROWN, a citizen of the United States, residing at Blackwoodtown, in the county of Camden and State of New Jersey, have invented a new and useful"Wagon-Perch-Crotch Coupling, of which the following is a specification.

My invention relates to a device for coupling the perch-pole and crotch ofthe runninggear of a wagon, by which is provided a safe,

reliable, and adjustable connection. A screwbolt is passed through an opening in the perch and crotch, and has screwed to it one end of a nut-arm,which rests on a washer to raise it conveniently above the crotch. The outer end of the arm has a conical opening, into which is fitted a like-shaped head of a suspended stay-bolt that has a flanged end for taking beneath the crotch.

0n reference to the accompanying sheet of drawings, making part of this speciflca tion, Figure 1 is a perspective view of my invention, in connection with a perch and crotch. Fig. 2 is a vertical and transverse section of the perch and crotch through the line a h, Fig. 1. Fig. 3 is a side elevation of my invention, the ends of the arm being sectioned to show the screw-connection and the conical fitting of the opposite end of the arm. Fig. 4 is a side elevation of the arm, its outer end being sectioned to show the conical opening. Fig. 5 is a sectioned elevation of the perch and crotch through the line (t Z), Fig. 1, (the other parts not being sectioned,) showing the position of the swinging bolt for unscrewing the arm; and Fig. (3 is a sectioned view through the line a b, Fig. 1", of the perch and crotch only for showing the bolt-opening.

Similar letters refer to similar parts in the several views.

A is the perch-pole, and B the crotch, of the running-gearof a wagon. Bearing against the bottom of the perch-pole A is the head 0 of a bolt, 0, that passes through an opening, d d, Fig. 6, in the perch and crotch, and has a screw, 6, Fig. 3, formed on its upper end for a female screw in that end of an arm,D. Be-

tween the crotch and the arm is a washer, E, for raising the arm above the crotch that it may be readily turned. The outer end of the nut-arm D has a conical opening, f, Fig. l, for the reception of a like-shaped head, g, of a flanged bolt, F, that is suspended freely from the arm, Figs. 3, 4, and 5.

The operation of my invention is as follows: The required length of the runninggear having been first determined, the opening (1 of the crotch Bis aligned over any opening, (Z, of the perch A, Figs. 1, 2, and 6, that will give the desired length. The bolt 0 is then passed through the opening d d, Fig. 6, and the washer E slipped over the projecting screw end 6. The nut-arm D is screwed on the bolt 0 by lifting the bolt F until its flange it rises above the crotch B, Fig. 5, which permits the arm to be turned on the screw e until the perch and crotch are firmly held together. The bolt F is afterward dropped until its taper head g rests in the like opening, f, in the arm and the flange 7L takes beneath the crotch, Figs. 1 and 2. A notch, i, in the side of the crotch permits the flange to drop without interference.

I do not confine myself to the elongated head 0 of the bolt 0 and its upturned tips j against the sides of the perch-pole A to keep the bolt from turning and unscrewing from the arm D. A head of another shape will serve. The washer E need not be used when that end of the arm has an extended hub or can otherwise be raised sufliciently high to clear the flange h of the boltF when the arm is turned for screwing or unscrewing. It is essential that the swinging bolt F should be of such dimensions as to fit loosely in the opening f of the arm. To that end it is not necessary that the said opening f and the head g of the bolt should be conical. Any shaped opening and head will suffice that will permit of a free motion of the bolt through the arm and hold it from dropping out. The nut-arm D serves for binding the perch-pole and crotch together, and the stay-bolt F not only operates the nut-arm for screwing and unscrewing, but serves to hold it from any loosening motion that may be caused by the running and jarring 0f the wagon. While ZU'IH,-D, and a loose stay-lmlt, F, for the pur- Hm flange 01: buflion 71 steadies The bolt F by pose shown and desm-lbod.
